Any idea what a SPT would look like for DS2?
I ask only because the things that DD has definitely been allergic to, she has tended to be over class III to, and also to have spectacular skin tests for.
Except milk. (Well, we can't be perfectly consistent, can we? Where would be the fun in that?)
I would just think that if he popped with a half-dollar sized wheal, along with RAST that high, you'd probably be about 95% confident even without a challenge, YK?
